I am renovating the basement in my house with a new "moisture-proof" construction. The house was built in 1966. I have removed most of the wooden structures, even in the basement ceiling to replace the insulation in the subfloor (which was previously wood shavings). However, I have left some old furring strips in the ceiling to attach the new ceiling to.
I have laid a new, level subfloor, and now that I have something to measure against, I find that the ceiling height varies significantly across the room... The difference is 1 cm over 1 m at worst. The reason is that the joists in the subfloor don't have a level underside, they are also mounted with mixed CC (anywhere from 45 to 60), and are not even parallel.
If I now install a ceiling (foiled particle boards 12x620x1200), I am, of course, worried that it will be noticeable that the ceiling height varies from 2.04 to 2.03 and back to 2.04 over 2 m of ceiling in the middle of the room.
So I have two questions - is such a difference noticeable, and if it is, what on earth can be done about it?

I don't think it's noticeable. And if it is noticeable, it's too minor to be worth doing anything about. In my experience, it's only renovation enthusiasts like myself who see flaws in the ceiling 
regular visitors to our home think everything looks awesome
So a ceiling in the basement is probably fine as it is with laminated chipboard if it's only off by 10 mm here and there.

Then I'll go ahead and set them up as planned!
I also follow the (sometimes a bit silly) philosophy of "do it perfectly when you're doing it anyway," but so far no one else besides me has seen the places where I've taken shortcuts. Except for my dad, but he's an architect and has redesigned villas for 40 years, so his attention to detail doesn't count.

No, other fools wouldn't notice, you and I would see that in each other's houses, but all those other people won't notice anything at all.viktordt said:Then I'll go ahead and set them up as I planned!
